It opens OK for me on a 10Mb .CR2 with only 32 Mb ram. But Shredboy is right in that usually C-Exception errors occur for me when memory is thin. Try opening it without any maps, on a cr2 with no morph targets, like one of the default child figures, to see if memory is the problem. Sounds like you got everything in the right folders (or you would get an "OBJ not found" type of error), but after repeated attempts, delete the .RSR for the object file (in the Geometries folder) and let Poser rebuild it. It may have become corrupted on the first attempt and even if you re-install the object file, Poser will ignore the .OBJ file and still load from any existing .RSR first.
